-2+y-z=-1 -2-2y+z=-7
Substitute -2 for x in the second and third equation.
y=1+z z=-5+2y
Solve these equations for y and z respectively.
z=-5+2\left(1+z\right)
Substitute 1+z for y in the equation z=-5+2y.
z=3
Solve z=-5+2\left(1+z\right) for z.
y=1+3
Substitute 3 for z in the equation y=1+z.
y=4
Calculate y from y=1+3.
x=-2 y=4 z=3
The system is now solved.
